【正文】 將立足于社會(huì)的我們也有非常大的意義。感覺做完之后非常累,但是也感覺這段時(shí)間過得非常充實(shí)!第五篇:化工原理課程設(shè)計(jì)化工原理課程設(shè)計(jì)摘 要 本次設(shè)計(jì)是針對(duì)二元物系的精餾問題進(jìn)行分析、選取、計(jì)算、核算、繪圖等,是較完 整的精餾設(shè)計(jì)過程。我們對(duì)此塔進(jìn)行了工藝設(shè)計(jì),包括它的輔助設(shè)備及進(jìn)出口管路的計(jì)算,畫出了塔板負(fù)荷性能圖,并對(duì)設(shè)計(jì)結(jié)果進(jìn)行了匯總。此次設(shè)計(jì)的篩板塔是化工生產(chǎn)中主要的氣液傳質(zhì)設(shè)備。此設(shè)計(jì)的精餾裝置包括精餾 塔,再沸器,冷凝器等設(shè)備,熱量自塔釜輸入,物料在塔內(nèi)經(jīng)多次部分氣化與部分冷凝進(jìn) 行精餾分離,由塔頂產(chǎn)品冷凝器中的冷卻介質(zhì)將余熱帶走。本次設(shè)計(jì)是精餾塔及其進(jìn)料預(yù) 熱的設(shè)計(jì),分離質(zhì)量分?jǐn)?shù)為 20%的苯甲苯溶液,使塔頂產(chǎn)品苯的質(zhì)量分?jǐn)?shù)達(dá)到 95%,塔 底釜液質(zhì)量分?jǐn)?shù)為 2%。綜合工藝操作方便、經(jīng)濟(jì)及安全等多方面考慮,本設(shè)計(jì)采用了篩板塔對(duì)苯甲苯進(jìn)行分 離提純,塔板為碳鋼材料,按照逐板計(jì)算求得理論板數(shù)為 12。根據(jù)經(jīng)驗(yàn)式算得全塔效率為 。塔頂使用全凝器,部分回流。精餾段實(shí)際板數(shù)為 10,提餾段實(shí)際板數(shù)為 13。實(shí)際 加料位置在第 11 塊板。精餾段彈性操作為 ,提餾段彈性操作為 。塔徑為 。通過板壓降、漏液、液泛、液沫夾帶的流體力學(xué)驗(yàn)算,均在安全操作范圍內(nèi)。確定了操作 點(diǎn)符合操作要求。關(guān)鍵詞:苯甲苯;精餾;負(fù)荷性能圖;精餾塔設(shè)備結(jié)構(gòu)I化工原理課程設(shè)計(jì)Abstract This design is in two yuan of the distillation analysis, selection, calculation, calculation and drawing, is a plete distillation design tower was process design, including its auxiliary equipment and import and export pipeline calculation, draw plate load performance diagram, and the design results are design of the sieve plate tower is the chemical industry in the production of gasliquid mass transfer design of rectifying device prises a distillation column reboiler, condenser and other equipment, heat from the reactor input, material in the column after repeated partial gasification and partial condensation distillation separation by top product condenser cooling medium to heat design of distillation column and its feed preheating design, separation and mass fraction of 20% benzeneII化工原理課程設(shè)計(jì) 前 言 課程設(shè)計(jì)是化工原理課程的一個(gè)非
